During an MR-guided breast intervention, placement of a needle or probe requires accurate localization of the target. To allow rapid identification of these errors, avoid unnecessary trauma to the patient, and minimize scanner time, a real-time MR acquisition and display was implemented to allow the physician to monitor both the progress of the insertion and the procedure itself, such as core needle biopsy or tumor ablation. Flexibility was added to adjust the scan plane in real-time and make tradeoffs between update display rate and image quality.
